Inventor: ELBEL KARL DR
IPC: C23C16/30
Filed: 1991-05-14
Abstract: Process is for the mfr. of honing and grinding elements with improved edge stability. One or more of the edges of the element, which consists of bonded abrasive grains, is provided with a layer of hard material. Also claimed are (1) a honing or grinding element of bonded abraisve grains, which has a hard metal layer on at least one face delimiting an edge of the grinding face; (2) the use of the above for honing metal surfaces, to prevent the formation of a coating of sheet metal. The layer of hard material, pref. comprising oxides, nitrides, carbides and/or borides, or carbon with a diamond structure, is applied by a physical or chemical deposition process. The most pref. hard materials comprise oxides, nitride, carbides and/or borides of Al, B, Si, Ti and/or W. ADVANTAGE - Eliminates the danger of rounding off the edges, and thus of forming a metal coating and other defects in honing, grinding and cutting operations.

Inventor: SEIDEL WILLI
IPC: B60W10/18
Filed: 1991-06-21
Abstract: A process is disclosed for controlling a preferably electro-hydraulically actuated infinitely variable transmission of a motor vehicle provided with an internal combustion engine. The transmission ratio is increased during braking, in particular when approaching curves. The observance of certain conditions therefor ensures a safe performance. The increase in the transmission allows the braking effect of the internal combustion engine to be better used, so that the service brake is discharged. Combined with a transmission ratio lock before, during and after curves, the vehicle provided with an infinitely variable transmission controlled according to the disclosed process can be accelerated with almost no delay when leaving a curve.

Title: Clutch disc with hub for motor vehicle - has automatic release of individual friction linings from counter pressure plate to prevent sticking
Inventor: BIER HELMAR
IPC: F16D13/64
Filed: 1992-06-23

Patent DE-4309115-A1 (DE)
Inventor: HOFBAUER PETER PROF DR ING
IPC: F23D11/40
Filed: 1993-03-23
Abstract: The invention relates to a method for operating an oil evaporation burner for heating boilers which, for the purpose of reducing pollutants, are operated with waste-gas recirculation from the combustion chamber (K) of the heating boiler into the burner. In the case of such oil evaporation burners, difficulties are caused by the waste-gas recirculation during the start-up phase in so far as the burner often goes out during the start-up phase. In order to overcome these difficulties, the recirculated waste-gas stream is interrupted during the start-up phase, to be precise in a pneumatic manner by forming barrier curtains from air which has been supplied. The oil evaporation burner intended therefor comprises a housing (1) with a funnel (3) for forming a swirling flow, there being arranged, on the funnel (3), at least one injector (5) for introducing the combustion air and taking in waste gases from the combustion chamber (K), and an oil-supply line (2) with nozzle (D) being directed into the funnel (3), and there being further arranged, in front of the injector (5), an air-supply chamber (6) with air-outflow openings (8) directed into the injector (5). Arranged on at least one injector (5) is at least one air-supply duct, such as small tubes (9), with openings (14) directed transversely into the inflow opening (5') of the injector (5), and the air-supply duct is provided with means for the controlled interruption of the air supply at the end of the start-up phase of the burner.

Title: Reusing old car tyres by using them in the production of rubber pipes
Inventor: KUPSA MIROSLAV
IPC: B29D23/00
Filed: 1993-04-14
Abstract: Old rubber tyres which are no longer able to used for protective purposes must be stored (giving rise to storage problems) or burned, which pollutes the environment. A further possibility is to produce a pipe from these tyres and thus progressively reduce the quantity of old tyres. At the same time it is the aim to produce a pipe which has a virtually unlimited service life and does not have to be produced from products which have very adverse effects on the environment during production (such as cement, ceramic etc). Because these pipes have no side effects on the environment, they are well suitable for conducting or diverting water in natural situations, or for melioration.
